[PATCH 2/6] scriptreplay: make Up/Down keys use a percentage instead of fixed amount

Using a fixed 0.1 amount made each subsequent Down-arrow key slow things
down _more_, and each subsequent Up-arrow key speed things up _less_.
It's nicer when each subsequent keystroke has the same relative effect.
